When you want to sing, play or practise with PDF digital sheet music you are usually faced with a few hurdles to overcome.

First of all you need to be well organised to keep all your PDF digital sheet music in one easy-to-find place. Even then it is sometimes difficult to immediately know just from the file titles, what-is-what in your sheet music folder.

When you want to play along to PDF digital sheet music away from the computer or tablet you have to print it out and consequently manually turn pages. On digital devices you need to move the music on with the keyboard, foot pedal or touch gesture as often it does not scroll automatically and you might loose your place in the music.


You might want to practise along to a metronome and need to either boot up a digital metronome, use an old wind-up metronome or perhaps a metronome on your mobile device. You might even use a music application like Garage Band, Logic, Audacity, Fruity Loops or similar to provide you with a steady rhythm. Another thing to think about.


Last but not least you might want to practise along to the original track, a backing track or minus one audio file. These might come in form of a CD for which you need either a traditional CD player or a laptop or desktop computer. The audio might be in digital format, very commonly in MP3 format and might be played on a computer, tablet or mobile device. Again, like with sheet music, you need to be well organised with your music practise audio files and hopefully all the MP3s are labelled in an obvious way for quick access.

Put all these elements together and you are ready for your music practise.

Sounds complicated? We agree, this is why we want to offer an alternative and much easier way to interact with your digital music education content. This is why we have come up with AudioSheetMusic™.

In the broadest sense KR player can help you to become a better musician? How, we hear you ask?

KR Player makes it easy for you to practice on the go. You no longer have to schlepp books, sheet music, CDs, iPods and a metronome with you everywhere you go. Tablets are small and portable and now they can contain all your AudioSheetMusic™. Everything you need is in one place. And what's more - you don't need to have an internet connection to play your KR files.

Will get you better grades. It doesn't matter if you are full time student at a school/university or a keen amateur - whatever your exams holds, buy or create your own AudioSheetMusic™ with the exam material and practice until you reach perfection.

Enhance your enjoyment of music practice. Not having to fiddle around  with multiple media - analog or digital - makes it a lot simpler and more fun to practice. You can immediately get stuck into practice mode whenever you fancy without having to boot up other applications or set up your practice station.

Help you to become better reader/understand music notation. As we are combining music notation with real audio it it clear that KR Player and KR Author are excellent sight-reading tools. Even if you don't want to become a proficient sight-reader you might want to become better at interpreting chord charts, chord symbols, chart geography and generally learn more about music notation by, for example singing along to the shape of a written melodies, all this is covered by our applications.

Play along with great musicians and backing tracks. We are aiming to have only high quality audio material on our in-app store - both in sound recording quality and performance. The Open Goldberg Variations are a good example of this. Listen and play along to world class recordings and musicians.

KR files help you to not get lost. Super helpful as the highlight bar always shows you where you are in relation to the audio. This is great to study parts or scores, even away from your instrument.

Organize your practice material. We all have been there - we downloaded a killer backing track and corresponding sheet music from the net or email and stored it somewhere on our hard drive. By the time we want to practice with this material we forgot what the individual files were called and more often than note, digital files are not exactly labelled in the most user friendly way. Your mp3 might be 'guitar track' and your PDF score might be '234567890987-34 guitar'. Combine these files from the off and create easily searchable KR Files and you will always find your practise material.
